2_01/2006Cover Picture: Design of Self-Assembling Peptide Nanotubes with Delocalized Electronic States (Small 1/2006)

The cover picture illustrates redox-promoted self-assembly of an eight-residue cyclic d,l-α-peptide bearing four 1,4,5,8-naphthalenetetracarboxylic diimide side chains into electronically delocalized peptide nanotubes hundreds of nanometers in length. The background picture was derived from an atomic force microscopy image of self-assembled cyclic peptide nanotubes adsorbed on mica. The supramolecular approach suggests a rational basis for the design and fabrication of composite 1D biomaterials with potential utility in optical and electronic devices. For more information please read the Communication “Design of Self-Assembling Peptide Nanotubes with Delocalized Electronic States” by M. R. Ghadiri and co-workers on page 99 ff.
